dilute-1I guette W. D. MENDENPIALL, OF FARMING'ION, ILLINOIS.

Lette/rs Patent No. 93,107, dated July 27, 1869.

.IMPROVED PRESS FOR OPERATING, BENDING, AND .SHAPING' DIES.

The Schedule Areferred to in these Letters Patent and making part of the same.

-To all whom 'it may. concern Be itknown that I,W.D.MENDEN1 1ALL, of Farmington, in the county of Fultom'and in the lState of Illinois, have invented a new and improved Press for Mouldin or Shaping Mould-Boards for Plows, and. for similar purposes; and do hereby declare that the following is affull, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and iu which- Figre lv represents a'perspective view.

Figure 2,- an elevation o f the same.` Figure 3, plan of the saine.

.Figure 4, elevation Aof working-part of same, showing the lever and rods, &c.

This invention consists of a square frame, A A, with an adjustable platform, C, which carries the lower half ofthe mould-block G, in which the mould-board of a plow is pressed or shaped.

Ihe upper half of the mould-block F is attached to the lower end of a vertical bar, E, which moves in guides D B, which latter act also as braces to keep the `frame intact.

lhis bar is actuated by a bent lever, a, the shortv arm of which is united to parallelrods b b, the latter being connected by theisupp'er ends, at d, with said bar E, the-lever being fulcrumed on a standard, j, on the stationary platform B.

Having now given the outlines of this device, I'will proceed with a more comprehensive description of the parts.

rlheplatform B is mortised, or otherwise secured to the four standards A A A- A of the frame.

Beneath this is a second platform, C, suspended to the former by means of bolts g g, 86e., with nuts h h, by which the distance between the platforms', or ratherthe mould-blocks, is adjusted, to obtain the proper throw of the lever a.

The upper platform B supports a standard, f, or fulcrum, for the angle t' ofthe bent lever a.

llhe handle of the latter, H, projects at a -right angle from the said lever, at this point, t'. e., the fulerum.

.The end of the short arm of the lever is connected with theupper part ofthe vertical bar E, by one or more bars, connected at each end with bolts, orequi'valent fastenings, to the bar E above, and the lever a. below.

The connection of this rod or rods with the vertical bar may be by means of ay plate of iron, carrying a strong staple for the bolt.

The short arm 'c of the lever may be so constructed as to allow the standard j, on which it is fulcrumed, to pass upwards through a slot or division of this part of the lever, asseen in fig. 4.

The operation of this machine is as follows:

The raisingof the handle H, of the lever c, throws up the bar E, carrying the upper mould-block F, by. the action ofthe rods b b, on the former.

The depression of the handle brings the point of the lever a, to which are attached the lower ends of the parallel rods b I), downwards, or nearer to the mould# blocks, pressing down with it, by means of said rods,

the vertical bar E, which carries the upper mouldblock F.

The bolts gg g'g are so adjusted as to give the lever a the vfull amount of its leverage in its pressure on the iron plate or mould-board, placed between the mouldblocks, to be shaped.

The full power exerted by the lever will be,- of course, near-the point at which theupperand lower ends of the rods b `b are ina line with the Afulcrum of the lever a.

The lower platform C may b`e notched at each'corner, to admit an angle of the post, or any similar device for s ecuri'ng it an .easy guide in proper position, when in the act `of being raised or lowered.

Having thus-fully described my invention,l Y

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a press forshapng the mouldboards orplates of plows, and for bending similar metal plates, Ste., the lever a, with its handle H, rod or rods b b, with their bolts and connections, the vertical bar or shaft E, with its shoe or head, at its lower end, the fulcrum or support f, of the lever a, and the gnides'or platforms B and D, all substantially as described and for the purposes set forth. 'A

2. In combination wlth the above, and working with them, the adjustable platform C, with its bolts g gggh;

or equivalent means for adjustment of this platform to the upper one, to suit mould-boards of any thickness to the full power of the lever, substantially as described and for the purposes set forth.

In testimony that Inclaim the' foregoing, I have hercunto set my hand, this 4th day of June, A. D. 1869. W. D. `MENDEN HALL.
